JN.1 vs KP.2 vs LP.8.1 got you confused?

Is anyone aware of hardware (or sw) differences between the 8020M (gen1) and 8020A (or perhaps even 8020) that could affect serial protocol handling?
The former occasionally appears to struggle with handling (too) regular display updates, and I'd be curious to understand why.

Does anyone in Europe need some TSI/8020-compatible serial adapters? I ended up making a few more as an experiment (& basket filler):

An attempt at visualising the impact of leakage (or faceseal penetration) on total penetration for a given respirator.
A lower bound for filtration efficiency (for **current** air cmp.) can be calculated from peak FF, and can in turn be used to estimate a lower bound on leakage.

UZH bietet Risikopersonen möglicherweise die RSV Impfung an (vermutl. Off-Label, und def. ohne Kostenübernahme): reisemedizin.uzh.ch/de/impfbuch-...
Hat da jemand Erfahrungen? Ist wohl nicht mehr der richtige Zeitpunkt dafür.

RSV steht für das Respiratorische Synzytialvirus, welches sehr ansteckend ist und eine Gefahr für Säuglinge darstellt. Die Impfung gibts bei uns am Zentrum für Reisemedizin UZH.

FFP2 vs FFP3: this SWPF-ish study suggests that they both offer equivalent protection:

Key limitation: includes only 2 manufacturers (for one: the FFP2 model was superior, for the other the FFP3 model was superior).

A 2024 manufacturer-funded study suggests that Bimervax XBB produces a similar response to Comirnaty XBB.
Which means: Bimervax might be a reasonable option *if* they can manage to produce updates and get them approved sooner...

I had been wondering why OSHA deleted their APF guide:
2. Popular Information has obtained archived versions of most of the deleted publications. Almost all of them are not associated with DEIA topics but appear to have been targeted because they include a DEIA-related keyword used in a completely different context.

A thread infection prevention, and iMasks ...
The frequent weld failures in Standart UA's iMasks have been discussed up and down Twitter and BSky. Having done my own analysis a bit over a year ago, I decided to get a new batch and see whether the design had been improved.

Das Luzerner Kantonsspital hat seine Internen Paxlovid/Remdesivir Richtlinien verschärft: seit November '24 ist eine Früh-Therapie nur noch bei schwerer Immundefizienz «meist indiziert» (weitere Risikogruppen nur bei fehlender Impfung, falls schon anderweitig Hospitalisiert).

I think I've finally figured out why the UK insists on FFP3s in healthcare, despite real-life data suggesting that there may be little advantage vs FFP2 **when fit testing has been performed** (compared to e.g. the US where N95 is acceptable).
